DxGrid.ColumnResizeMode Property

Specifies whether and how users can resize Grid columns.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(GridColumnResizeMode.Disabled)]
[Parameter]
public GridColumnResizeMode ColumnResizeMode { get; set; }

Property Value

Type	Default	Description
GridColumnResizeMode	Disabled	A GridColumnResizeMode enumeration value.

Available values:

Name	Description
Disabled	A user cannot resize columns.
NextColumn	When a user resizes a column, the width of the column to the right changes (considering the MinWidth value), but the Grid’s total width does not change. Users cannot change the width of the rightmost column.
ColumnsContainer	When a user resizes a column, all other columns retain their widths, but the width of the container that stores all Grid columns changes.

Remarks

If the ColumnResizeMode property is set to Disabled (the default value), a user cannot change a column’s width at runtime.

To enable column resize operations, set the ColumnResizeMode property to one of the following values:

• NextColumn – When a user resizes a column, the width of the column to the right changes (considering the MinWidth value), but the Grid’s total width does not change. Users cannot change the width of the rightmost column.

  

• ColumnsContainer – When a user resizes a column, all other columns retain their widths, but the width of the container that stores all Grid columns changes.

  The Grid fixes column widths specified in percentages. Fixed values are calculated in pixels. If the sum of all column widths (considering the MinWidth value) is greater than the container’s total width, Grid displays the horizontal scrollbar. Otherwise, an empty space remains to the right.

  

If allowed, the following column resize operations are available to users:

• Drag a column header’s right border.
• Double-click a column’s right border to apply optimal width based on the column’s content.

Note that a column before a fixed column is not resizable.

The code below activates NextColumn resize mode:
